48V Telecom and Server Power
The TPS26600RHFR is ideal for 48V telecom and server power distribution, where hot-swap capability and overcurrent protection are essential. Its 60V input range accommodates 48V buses with transients, and the adjustable current limit enables precise inrush control during board insertion. The device's integrated protection features reduce external component count, saving board space in dense server racks. The fault output can trigger system alerts, and the enable pin allows sequenced power-up. With a low on-resistance, it minimizes voltage drop and power dissipation, improving overall system efficiency.

Key Differentiators
- Integrated reverse polarity protection down to -60V (vs LTC4366)
- Wide input voltage range of 4.2V to 60V (vs TPS26602RHFR)
- Low on-resistance of 150mΩ (vs LTC4366)
Design Notes
During current limiting, the TPS26600RHFR can dissipate significant power. For example, at 48V input and 2A current limit, power dissipation can be up to 96W. The VQFN-24 package has a thermal resistance of approximately 30°C/W (typical). Ensure adequate PCB copper area and thermal vias to keep junction temperature below 125°C. Use the exposed pad connected to GND for heat sinking.
Place the current-limit resistor (RILIM) close to the ILIM pin to minimize parasitic inductance. Use Kelvin connections for accurate current sensing. Input and output capacitors should be placed as close as possible to the IN and OUT pins. A 0.1µF ceramic capacitor on the EN pin is recommended for noise filtering. Follow the layout guidelines in the datasheet for optimal performance.
Do not exceed the absolute maximum input voltage of 62V. Ensure the current-limit resistor is properly sized for the desired current limit; an incorrect value can lead to insufficient protection or nuisance trips. The FLT pin is open-drain and requires a pull-up resistor. Verify the fault timer settings to avoid false triggering during inrush. Always refer to the datasheet for complete design guidelines.
